[PATCH v1 4/5] board: rock5b-rk3588: enable USB-C in operating system

[Sebastian Reichel]

Since older U-Boot releases do not negotiate USB PD, the kernel
DT may not enable the USB-C controller by default to avoid a
regression. The plan is to upstream it with 'status = "fail";'
instead. U-Boot should then mark it as 'status = "okay";' if
it negotiated USB PD.

FWIW, I have not yet send the kernel patch, since I want the following
patch to be applied first:
